This document outlines guidelines for calculating package weight for logistics partners. Logistics partners charge for fulfillment based on the volumetric weight or actual weight of packaged products, whichever is higher. Volumetric weight is calculated based on the length, breadth and height of packages and factors in whether the weight is below or above 5 kg. Examples are provided to demonstrate how volumetric weight is calculated for packages weighing 600g and 25kg based on their dimensions. Finally, the document lists the package weight fees charged by fulfillment partners in different weight slabs.
